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:
69 x 69 x 69 x 69 x ... (for a total of 78 times) = 269295488349391092541987660235903329574528403059223255660156961149106390876489285577521102582910606113481675726676670281221878227108633476891241
Therefore, 69 to the power of 78 is 269295488349391092541987660235903329574528403059223255660156961149106390876489285577521102582910606113481675726676670281221878227108633476891241.
