Question

Solve:
1) (3²9) x (7 X 10-4)
2) (4³ x 3² ÷ 3)
3) (9²+5) 83 +1 2
4) (3²x3 +4 ÷2) - 1
5) 6²÷(2-8) +1-8​

Answer 1

Answer:

1) (3²9)×(7×10-4)

(3×3 9)× (7×10-4)

(9 9)×(7×10=70-4)

9 9×66

3534

Answer 2

Answer:

1) 5346

2) 192

3) 7150

4) 28

5) -13

Step-by-step explanation:

1)

$(3^2*9)*(7*10-4)\\ = (9*9)*(7*10-4)\\= 81*(7*10-4)\\= 81*(70-4)\\= 81*(66)\\= 5346$

2)

$4^3*3^2/3\\\\= 64\cdot\frac{{3}^{2}}{3}\\\\= 64\cdot\frac{9}{3}\\\\ = 64\cdot\frac{\left(3\cdot3\right)}{\left(1\cdot3\right)}\\\\= 64\cdot3\\= 192$

3)

$(9^2+5) 83 +12\\= 86\cdot \:83+12\\=7138+12\\ = 7150$    

4)

$(3^2*3+4/2)-1\\\\= \left({3}^{2}\cdot3+\frac{\left(2\cdot2\right)}{\left(1\cdot2\right)}\right)+-1\\\\=\left({3}^{2}\cdot3+2\right)+-1\\=\left({3}^{2}\cdot3+2\right)+-1\\=\left({3}^{2}\cdot{3}^{1}+2\right)+-1\\=\left({3}^{\left(2+1\right)}+2\right)+-1\\=\left({3}^{3}+2\right)+-1\\=\left(27+2\right)+-1\\=28$

5)

$6^2/(2-8)+1-8\\\\=6^2/(-6)+1-8\\=36/-6+1-8\\=-6+1-8\\=-5-8\\=-13$
