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:
66 x 66 x 66 x 66 x ... (for a total of 99 times) = 1364110709824360139509742746819273151643580629979110522027723121541178534271538223473966504503718361847509635163230577468612601611179036343949216629735369600444335031742756118593536
Therefore, 66 to the power of 99 is 1364110709824360139509742746819273151643580629979110522027723121541178534271538223473966504503718361847509635163230577468612601611179036343949216629735369600444335031742756118593536.
