The 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
So re-applying these steps to our particular problem, we first convert our word problem to a base-exponent form of:
To simplify this, all that is needed is to multiply it out:
39 x 39 x 39 x 39 x ... (for a total of 70 times) = 2368767805694375722350036623180045667806813973955977581181833011381248316831733203331516143712511660776878101201
Therefore, 39 to the power of 70 is 2368767805694375722350036623180045667806813973955977581181833011381248316831733203331516143712511660776878101201.
