The first step a math tutor would suggest 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:
95 x 95 x 95 x 95 x ... (for a total of 90 times) = 9888364709658990855807805490546081059228529853829308510672125412492228647545194709102371593863615498839273627354204966494704587780980296375654692297985093318857252597808837890625
Therefore, 95 to the power of 90 is 9888364709658990855807805490546081059228529853829308510672125412492228647545194709102371593863615498839273627354204966494704587780980296375654692297985093318857252597808837890625.
