Question

Evaluate the following expressions given

Answer 1

The answers are:

i) 17

ii) 315

iii) 29

iv) 104.64

i) (5a-2b)

= (5)(2) - (2)(-3.5)

= 10 + 7

= 17

ii) 3d(8-7c)

= 3(105)(8-7(5/7))

= 3(105)(1)

= 315

iii) 6^0 - 8b

= 1 - 8(-3.5)

= 1 + 28

= 29

iv) |d-45a^{2}(c^{5})|

= |105-45(2^{2})((5/7)^{5})|

= |105 - 45(4)(125/3125)|

= |105 - 1800/3125|

= |105 - 36/625|

= 104.64

Therefore, the answers are:

i) 17

ii) 315

iii) 29

iv) 104.64
