Question

48+4^2+3/5
Help me it asks to evaluate

Answer 1

325/3

Explanation:

`48+4^2+(3)/(5)\\\\\mathrm{Convert\:element\:to\:fraction}:\quad \:48=(48\cdot \:5)/(5)\\\\=(48\cdot \:5)/(5)+(3)/(5)\\\\\mathrm{Since\:the\:denominators\:are\:equal,\\\\\:combine\:the\:fractions}:\\\\\quad (a)/(c)\pm (b)/(c)=(a\pm \:b)/(c)\\\\=(48\cdot \:5+3)/(5)\\\\48\cdot \:5+3=243\\\\=4^2+(243)/(5)\\\\=16+(243)/(5)\\\\=(16\cdot \:5)/(5)+(243)/(5)\\\\=(16\cdot \:5+243)/(5)\\\\16\cdot \:5+243=323\\\\=(323)/(5)`
