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:
49 x 49 x 49 x 49 x ... (for a total of 91 times) = 6424558419764364314812862549292357551272958886974535323941452800880754378959647257357647038300523145238385190905160291104871496886392334465033172862892049
Therefore, 49 to the power of 91 is 6424558419764364314812862549292357551272958886974535323941452800880754378959647257357647038300523145238385190905160291104871496886392334465033172862892049.
