Answer 1

Answer: 9

[ (81)½ { 64⅓ + 125⅓ } ] ½

We know that:

81½ = √81 = 9

64⅓ = ³√64 = 4

125⅓ = ³√125 = 5

Thus,

[ (81)½ { 64⅓ + 125⅓ } ]½

= [ (9) { 4 + 5 } ]½

= [ 9 × 9 ]½

= [81]½

= √81

= 9

Thus, the answer is 9.

Answer 2

Answer:

Step-by-step explanation:

(81)½ { 64⅓ + 125⅓ } ] ½

We know that:

81½ = √81 = 9

64⅓ = ³√64 = 4

125⅓ = ³√125 = 5

Thus,

[ (81)½ { 64⅓ + 125⅓ } ]½

= [ (9) { 4 + 5 } ]½

= [ 9 × 9 ]½

= [81]½

= √81

= 9

Thus, the answer is 9.
