Q.34 log 1.156 + 2 log 4 – log 1 = …sapi banh, ga ad yg req_-…

³⁴log 1.156 + ²log 4 – log 1 =

= ³⁴log 34² + ²log 2² – 0

= (1 × 2) + (1 × 2) – 0

= 2 + 2 – 0

= 4 – 0

= 4

$rm ^{34} log : 1.156 + : ^{2} log : 4 - log : 1$

$rm = : ^{34} log : {34}^{2} + : ^{2} log : {2}^{2} - : ^{10} log : 1$

$rm = : 2 cdot : ^{34} log : {34}+ : 2 cdot : ^{2} log : {2} - :0$

$rm = : 2 cdot : cancel{^{34} log : {34}}+ : 2 cdot : cancel{^{2} log : {2} }- :0$

$rm = 2 + 2$

$rm = 4$
