Exponents Test (6.14)

Exponential form represents repeated multiplication of a base by itself, indicated by an exponent. For example, 2^3 means 2 multiplied by itself 3 times. Thus, the correct answer is 'Exponential form'.

Exponents represent repeated multiplication. For example, 2^3 means 2 multiplied by itself 3 times (2 x 2 x 2). Therefore, the operation used with exponents is multiplication.

The base of a number in exponential notation is the number itself before the exponent. For $$8^7$$ , the base is 8; for $$7^9$$ it's 7; for $$25^{10}$$ , it's 25; and for $$12^4$$ , it's 12. Thus, the correct bases are 8, 7, 25, 12.

The expression 5 x 5 x 5 x 5 x 5 x 5 means multiplying 5 by itself 6 times. In exponential form, this is written as $$5^6$$ , which is the correct choice.
