Write Equation: Write down the given equation.The given equation is 7792=34×722×r3.
Simplify Right Side: Simplify the right side of the equation by multiplying the fractions.(34)×(722)=(3×74×22)=(2188).So, the equation becomes (7792)=(2188)×r3.
Multiply by 7: Multiply both sides of the equation by 7 to eliminate the denominator on the left side.7792×7=2188×r3×7.This simplifies to 792=2188×7×r3.
Calculate Value: Calculate the value of 88×7.88×7=616.So, the equation now is 792=21616×r3.
Divide by Fraction: Divide both sides of the equation by (616)/(21) to solve for r3.792÷(616)/(21)=r3.
Calculate Value: Calculate the value of 792÷(21616). To divide by a fraction, multiply by its reciprocal. So, we multiply 792 by (61621). 792×(61621)=r3.
Simplify Fraction: Calculate the value of 792×61621.792×61621=61616632.
Take Cube Root: Simplify the fraction 61616632. 61616632=27. So, the equation now is 27=r3.
Calculate Cube Root: Take the cube root of both sides to solve for r.r=327.
Calculate Cube Root: Take the cube root of both sides to solve for r.r=327.Calculate the cube root of 27.327=3.So, r=3.
