Step-by-step explanation:
Evaluate each expression is very simple concept in math. When you substitute a particular value for each variable and then act the operations called evaluating expression.
c) 1 week x 7 days/1 week x 24hr/1 day x 60min/1hr x 60s/1min =
If you solved it, you would get 604,800, which is correct.
Step-by-step explanation:
(x^4)^3=(x^3)^4 , true
=> x^(4×3) = x^(3×4) = x^12
13^4 x 13^7= (13^4)^7, false
13^(4+7) = 13^11
(13^4)^7 = 13^(4×7) = 13^28
y^5 x y^0/y^3=(y^2)^1 , true
y^5 x y^0/y^3 = y^(5+0-3) = y^2
(y^2)^1 = y^(2×1) = y^2
q^0 x q^5/q^2=(q^3)^2/q^3, true
q^0 x q^5/q^2= q^(0+5-2)= q^3
(q^3)^2/q^3 = q^(3×2-3) = q^3
