Understand the problem: Understand the problem.We need to find the product of the fourth roots of two numbers: 31 and 48. This means we will calculate the fourth root of each number and then multiply the results together.
Calculate 31: Calculate the fourth root of 31. The fourth root of 31 is the number that, when raised to the power of 4, gives 31. Since 1 raised to any power is 1, the fourth root of 31 is simply the fourth root of 1 divided by the fourth root of 3.
Calculate 48: Calculate the fourth root of 48.The fourth root of 48 is the number that, when raised to the power of 4, gives 48. We can simplify this by finding the prime factorization of 48 and then seeing if any groups of four identical factors emerge.48=2×24=2×2×12=2×2×2×6=2×2×2×2×3We have a group of four 2's, so the fourth root of 48 is 2× the fourth root of 3.
Multiply roots: Multiply the two fourth roots together.Now we multiply the fourth root of 31 from Step 2 with the fourth root of 48 from Step 3.431 * 448 = 4431 * 2∗43
Simplify expression: Simplify the expression.We can see that the fourth root of 3 in the denominator and one in the numerator will cancel each other out, leaving us with:(41/43)×(2×43)=2×(41)Since the fourth root of 1 is 1, we are left with:2×1=2
