Question

simplify:(-5)^2×2^3,(-4)^2×3^3×(-2)^3,7^2×(-10)^3​

Answer 1

Answer:

(i) 200

(ii) -3456

(iii) -49000

Step-by-step Explanation:

$(i) \: ( - 5) {}^{2} \times {2}^{3} = 25 \times 8 = 200$

$(ii) \: ( - 4) {}^{2} \times {3}^{3} \times { (- 2)}^{3} = 16 \times 27 \times - 8$

$= - 3456$

$(iii) \: {7}^{2} \times { - 10}^{3} = 49 \times - 1000 = - 49000$
