(53)-8 First use the rule for an exponential raised to a power: When an exponential is raised to a power itself, the expression is simplified by writing the base of the exponential inside the parentheses with an exponent equal to the product of the two exponents, and removing the parentheses. So we multiply the 3 by the -8 and have this 5-24 Now use these rules: To make a negative exponent positive, 1. Give it a 1 multiplier and a 1 denominator:2. (a) If the negative exponent is in the NUMERATOR, move it to the DENOMINATOR and change the sign of the exponent to positive. (b) If the negative exponent is in the DENOMINATOR, move it to the NUMERATOR and change the sign of the exponent to positive. This is the case 2(a), so we move the from the numerator to the deminator and change the exponent from -24 to +24: Now we can erase the 1 in the denominator but not in the numerator: Edwin
