3^-5×10^-4×125/5^-7×6^-5×2
Answers
Answer:
3125
————————— = 0.00005
(210•310)
Step-by-step explanation:
Step 1 :
1.1 6 = 2•3
(6)-5 = (2•3)(-5) = (2)(-5) • (3)(-5)
Equation at the end of step 1 :
125
(((3-5)•(10-5))•—————)•((2)(-5)•(3)(-5))
(5-7)
Step 2 :
Equation at the end of step 2 :
125
(((3-5)•(10-5))•———————)•((2)(-5)•(3)(-5))
(5)(-7)
Step 3 :
1
Divide 125 by ——
57
Raising to a Power :
3.1 53 multiplied by 57 = 5(3 + 7) = 510
Equation at the end of step 3 :
(((3-5) • (10-5)) • 510) • ((2)(-5)•(3)(-5))
Step 4 :
4.1 10 = 2•5
(10)-5 = (2•5)(-5) = (2)(-5) • (5)(-5)
Equation at the end of step 4 :
(((3-5) • ((2)(-5)•(5)(-5))) • 510) • ((2)(-5)•(3)(-5))
Step 5 :
Equation at the end of step 5 :
(((3)(-5) • ((2)(-5)•(5)(-5))) • 510) • ((2)(-5)•(3)(-5))
Step 6 :
Multiplying exponents :
6.1 25 multiplied by 25 = 2(5 + 5) = 210
Multiplying exponents :
6.2 35 multiplied by 35 = 3(5 + 5) = 310
Final result :
3125
————————— = 0.00005
