Step by Step Solution
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "^-6" was replaced by "^(-6)".
(2): "2.8" was replaced by "(28/10)".
Step 1 :
1.1 10 = 2•5
(10)-6 = (2•5)(-6) = (2)(-6) • (5)(-6)
Equation at the end of step 1 :
28
—— • ((2)(-6)•(5)(-6))
10
Step 2 :
14
Simplify ——
5
Equation at the end of step 2 :
14
—— • ((2)(-6)•(5)(-6))
5
Step 3 :
Multiplying exponents :
3.1 51 multiplied by 56 = 5(1 + 6) = 57
Dividing exponents :
3.2 21 divided by 26 = 2(1 - 6) = 2(-5) = 1/25
Final result :
7
——————— = 2.80000 • 10-6
(57•25)
