Question

5×64^-1/2(64^1/2+64^3/2​

Answer 1

Answer:

325

Step-by-step explanation:

64^-1/2 =[8^2]^-1/2 =8^-1 =1/8

64^1/2 =[8^2]^1/2 =8

64^3/2 =[[8]^2]^3/2​ =8^3 =512

5×64^-1/2(64^1/2+64^3/2​ = 5/8 { 8 +512 }

                                            =5/8[520]

                                            =5[65]

                                           =325

Answer 2

Hey mate here we go

$5 \times {64}^{ - \frac{1}{2} } ( {64}^{ \frac{1}{2} } + {64}^{ \frac{3}{2} } ) \\ = 5 \times ( \frac{1}{ \sqrt{64} })( \sqrt{64} + \sqrt[3]{64}) \\ = 5 \times \frac{1}{8} \times (8 + 512) \\ = \frac{5}{8} \times (520) \\ = 5 \times 65 \\ = 325 \\ \: this \: is \: ur \: ans \: \\ i \: hope \: this \: will \: help \: u \\ plz \: mark \: my \: ans \: as \: brainliest \\ ty$
