The digits base is 7 then we should convert them into base 6.
The exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logbn.
Here the conclusion is that there are many bases in the mathematics so what will happen is that we should convert these bases. For example, we have to convert base 10 of a number which is called decimal number can be converted into binary number whose base is 2 and after then if the digits base is 7 then we should convert them into base 6.
First, she distributed Which gave her Then, she combined like terms Which gave her Then, she subtracted from both sided Which gave her Then, she added to both sides Which gave her And finally sh edivided 32 by 2 and got hope this helps if you have any questions please pm me :)
