Q. Simplify. Express your answer using a single exponent.(7u5)2
Apply Power Rule: Apply the power to a power rule.When raising a power to another power, we multiply the exponents. For the expression (7u5)2, we apply this rule to the variable u.(7u5)2=72×(u5)2
Calculate 72: Calculate 72.72 is 7 multiplied by itself.72=7×7=49
Calculate (u5)2: Calculate (u5)2. We multiply the exponents for u. (u5)2=u(5×2)=u10
Combine Results: Combine the results from Step 2 and Step 3.We have found that 72=49 and (u5)2=u10. Now we combine these to express the simplified form of the original expression.(7u5)2=49u10
