Answer :

Answer:

log3 4

Step-by-step explanation:

To write the two expressions as a single logarithm, we use the division law of logarithms since they are in the same base already.

Hence, log3 40 - log3 10 = log3 (40/10) = log3 4

An expression [tex]\boldsymbol{\log_3 (40)-\log_3 (10)}[/tex] can be written as a single expression as equal to [tex]\boldsymbol{\log_3 4}[/tex]

The logarithm is defined as the inverse function to exponentiation.

The logarithm of a given number [tex]a[/tex] to the base '[tex]b[/tex]' is the exponent indicating the power to which the base '[tex]b[/tex]' must be raised to obtain the number [tex]a[/tex].

Given expression is [tex]\log _3(40)-\log _3(10)[/tex].

Use the formula: [tex]\boldsymbol{\log _a(b)-\log _a(c)=\log_a\left ( \frac{b}{c} \right )}[/tex]

Put values of  [tex]a,b,c[/tex] as [tex]3,40,10[/tex] respectively.

[tex]\log _3(40)-\log _3(10)=\log_3\left ( \frac{40}{10} \right )[/tex]

                              [tex]=\boldsymbol{\log_3 4}[/tex]

So, the expression [tex]\log_3 (40)-\log_3 (10)[/tex] can be written as a single expression as equal to [tex]\log_3 4[/tex]
