Question

I am having trouble with question 7 onwards to q10 anyone mind helping/teach me?

Answer 1

~7)~
$(3×4×5) =1.585 + 2 + 2.322 =5.907$
~8)
$(3÷2÷5) =1.585 - 1 - 2.322 =-1.737$
9)$3log7(2) -2log7(3) + 4log7(3) -2log7(2) =0.356+2(0.565) =1.486$
9)$x(x+2)=8 x=2$
10)$x/(2x+3)=1/9 9x=2x+3 x=3/7$

Hope this helps
