Answer: see below (some answers maybe wrong because of unclear image) remeber ^ = to the power of
Step-by-step explanation:
1.
a) 3^4 = 3*3*3*3 = 9*9 = 81
b) 125°+ 5^2 = 125 + 5*5 = 125 + 25 = 150°
c) 2^-5 = 1/2 ^5 (∵ x^-y = 1/x ^ y )
d) 11^4 * 11^-2 = 11^(4 + (-2) = 11^(4-2) = 11^2 = 11*11 = 121 (∵ x^y * x^z = x^(y+z) )
e) 1/7^(-4) = 1/7 ^ (-4) 7/1 ^ 4 = 7*7*7*7 = 2401 (∵ x^-y = 1/x ^ y )
2. 1723.56 = 1 * 10^3 + 7 * 10^2 + 2 * 10^1 + 3 * 10^0 + 5 * 10^ -1 + 6 * 10^-2
3. 4^5 * 2^3 * 2^-6 = (2*2)^5 * 2^3 * 2^-6 = 2^5 * 2^5 * 2^3 * 2 ^ -6
2^(5+5+3-6) = 2^ 7 (∵ x^y * x^z = x^(y+z) )
Rest see in the attachment (pdf)
