Q. Write the expression as a whole number with a negative exponent. Do not evaluate the expression.1561
Identify base and exponent: Identify the base and the exponent in the given expression 1561.The base is 15 and the exponent is 6. The expression is in the form of a fraction where 156 is in the denominator.
Apply negative exponent rule: Apply the negative exponent rule to rewrite the expression.The negative exponent rule states that a−m=am1. To write 1561 with a negative exponent, we can apply this rule in reverse, which gives us 15−6.
Check expression: Check the expression to ensure it is written as a whole number with a negative exponent.The expression 15−6 is indeed a whole number (15) with a negative exponent (−6), and it is equivalent to the original expression 1561.
