Q. Express in simplest radical form.7560Answer:
Factor and Simplify: Simplify the square root of 560.To simplify the square root of 560, we need to factor 560 into its prime factors and look for pairs of the same number, since the square root of a pair of numbers is just that number.560=2×280560=2×2×140560=2×2×2×70560=2×2×2×2×35560=2×2×2×2×5×7Now we can pair the 2s and take them out of the square root.560=2×2×2×2×5×7560=2×2×5×7560=4×35
Simplify Square Root of 7: Simplify the square root of 7. The square root of 7 cannot be simplified further since 7 is a prime number. 7=7
Divide Simplified Square Roots: Divide the simplified square root of 560 by the square root of 7. Now we divide 4×35 by 7. (4×35)/(7) We can simplify this by dividing the square root of 35 by the square root of 7. (4×35)/(7)=4×(35/7)
Simplify Division of Square Roots: Simplify the division of the square roots.We can simplify 35/7 by recognizing that 35 is the same as 5×7 and we can divide by 7.35/7=5×7/735/7=5
Multiply by 4: Multiply the result by 4.Now we multiply the simplified square root by 4.4×5This is the simplest radical form of the original expression.
