Q. Select the answer which is equivalent to the given expression using your calculator.(32b)52−10a23a=16 and b=2439160−9160−2716027160
Substitute Given Values: First, let's substitute the given values of a and b into the expression.a=16b=243The expression becomes (−10×163/2)/(32×2432/5).
Simplify Exponents: Now, let's simplify the exponents.1623 means the square root of 16 raised to the 3rd power. Since the square root of 16 is 4, we have (43).24352 means the 5th root of 243 squared. Since the 5th root of 243 is 3, we have 162.The expression now is 163.
Calculate Powers: Next, we calculate the powers.43=4×4×4=6432=3×3=9The expression simplifies to (−10×64)/(32×9).
Multiply Numbers: Now, let's multiply the numbers.−10×64=−64032×9=288The expression is now −640/288.
Simplify Fraction: Finally, we simplify the fraction−640/288 by dividing both the numerator and the denominator by their greatest common divisor, which is 32.−640/32=−20288/32=9The simplified expression is −20/9.
