(8*4*2/8*7)^2 x (8^0/7^-3)^3 x 7^-9
Simplify the equations:
(8*4*2/8*7)^2 = (64/56)^2 = (8/7)^2
(8^0/7^-3)^3 = (1/7^-3)^3 = 7^9
Now you have :
(8/7)^2 x 7^9 x 7^-9
Multiply 7^9 x 7^-9 by adding the exponents to get 7^0, which = 1
Now you have:
(8/7)^2 x 1
(8/7)^2 = (8x8) / (7x7) = 64/49
64/49 x 1 = 64/49
This is the ans plus u can use maths from Microsoft app for these type of questions
Answer:
∠B = ∠E
Step-by-step explanation:
If ΔABC ≅ ΔDEF, then:
∠A = ∠D
∠B = ∠E
∠C = ∠F
(pair of corresponding angles are congruent)
The answer is B, 5*2*30. Hope this helps
