Answer: 8 to the power of 3 can be expressed as 83 = 8 × 8 × 8 = 512.
We know that 82 = 8 × 8. A negative exponent tells us, how many times we have to multiply the reciprocal of the base. Consider the 8-2, here, the base is 8 and we have a negative exponent (-2). 8-2 is expressed as 1/8 × 1/8 = 1/82.
Formula – How to Calculate Exponent 8
The exponent 8 of a number is found by multiplying that number by itself 8 times.
The negative sign on an exponent means the reciprocal. Think of it this way: just as a positive exponent means repeated multiplication by the base, a negative exponent means repeated division by the base. So 2^(-4) = 1/(2^4) = 1/(2*2*2*2) = 1/16. The answer is 1/16.
How do you represent the power of 3? To represent the power of 3, add an exponent of 3 to the base number. To find the result, multiply the base number by itself 3 times.
Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.
Answer: 8 to the power of 3 can be expressed as 83 = 8 × 8 × 8 = 512.
The law of negative exponents states that, when a number is raised to a negative exponent, we divide 1 by the base raised to a positive exponent. The general formula of this rule is: a -m = 1/a m and (a/b) -n = (b/a) n. Below are examples of how negative exponent rule works: 2 -3= 1/2 3 = 1/ (2 x 2 x 2) = 1/8 = 0.125.
Example: 8-1 = 1 ÷ 8 = 1/8 = 0.125.
P = V X I . Here P is power in watts. V is voltage in volts. I is current in amps.
The Power Rule for Exponents: (am)n = am*n. To raise a number with an exponent to a power, multiply the exponent times the power. Negative Exponent Rule: x–n = 1/xn.

Answer: The value of 2 raised to 8th power i.e., 28 is 256.
If the power is even, then the result will be positive. If it is odd, then the result is negative. Here, we know that 2 is even. Hence, any negative number to the power of 2 is positive.
Answer: 5 to the power of negative 2 is 0.04.
2 to the negative 3rd power is 1/8, or . 125 in decimal form.
Answer: 10 to the power of negative 3 is 0.001.
Answer: 1/4 is the value hope it helps......
Do you know what the square root of 8 to the power of 3 is? To solve the problem, we need to take the square root of 8. Then, we take that value and multiply by itself 3 times. So essentially, square root of 8 to the power of 3 = (2.828 x 2.828 x 2.828) = 22.627.
Answer: 7 to the power of 3 can be expressed as 73 = 7 × 7 × 7 = 343.
8 1/3 = 8 1/3 = 8 · 3 + 1/3 = 24 + 1/3 = 253 = 8 13 ≅ 8.3333333.
