Question

pls do solve it guys ....pls....​

Answer 1

Step-by-step explanation:

$log_{2}a = 3 \\ {2}^{3} = a$

Therefore, a = 8

$log_{3}b = 2 \\ {3}^{2} = b$

Therefore, b=9

$log_{4}c = 1 \\ {4}^{1} = c$

Therefore, c = 4

Now,

$3a + 2b - 10c \\ 3 \times 8 + 2 \times 9 - 10 \times 4 \\ 24 + 18 - 40 \\ 42 - 40 \\ 2$

Therefore, the answer is 2.

Hope it helps...
