Solution: 81 to the Power of 18 is equal to 2.252839954493917e+34MethodsStep-by-step: finding 81 to the power of 18The first step is to understand what it means when a number has an exponent. The “power” of a number indicates how many times the base would be multiplied by itself to reach the correct value. The second step is to write the number in the base-exponent form, and lastly calculate what the final result would be. Consider the example of 2 to the power of 4: in exponent form that would be 242^424. To solve this, we need to multiply the base, 2 by itself, 4 times - 2⋅2⋅2⋅22\cdot2\cdot2\cdot22⋅2⋅2⋅2 = 16. So 24=162^4 = 1624=16.So re-applying these steps to our particular problem, we first convert our word problem to a base-exponent form of:811881^{18}8118To simplify this, all that is needed is to multiply it out:81 x 81 x 81 x 81 x ... (for a total of 18 times) = 2.252839954493917e+34Therefore, 81 to the power of 18 is 2.252839954493917e+34.Related exponent problems:Here some other problems that you can read and practice with!What is 6 to the Power of 95?What is 22 to the Power of 69?What is 9 to the Power of 91?What is 30 to the Power of 42?What is 19 to the Power of 5?
