10[4 times 10 divided by (6^2-4^2) +1]

19

Step-by-step explanation:

10[4 times 10 divided by (6^2-4^2) +1]

First you would multiply 6 x 6 = 36

10[4 times 10 divided by (36-4^2) +1]

Second you would multiply 4 x 4 = 16

10[4 times 10 divided by (36-16) +1]

Third you would subtract 36 - 16 = 20

10[4 times 10 divided by 20 +1]

Fourth you would add 20 + 1 = 21

10[4 times 10 divided by 21]

Fifth you would multiply 4 x 10 = 40

10[40 divided by 21]

Sixth you would divide 40 divided by 21 = 1.90

10[1.90]

Seventh you would multiply 10 x 1.90 = 19

Your answer would be 19.
