x +87 * pi ^ 3 * 43/76-91 +51 / 97 ^ 2 = sqrt (82 * 65pi)

Hi calculator353

 Is the you question or do you need to put more brackets in there somewhere?

$$x+87\pi^3*\frac{43}{76}-91+\frac{51}{97^2}=\sqrt{82*65\pi}$$

$${\frac{{\mathtt{87}}{\mathtt{\,\times\,}}{{\mathtt{\pi}}}^{{\mathtt{3}}}{\mathtt{\,\times\,}}{\mathtt{43}}}{{\mathtt{76}}}}{\mathtt{\,-\,}}{\mathtt{91}}{\mathtt{\,\small\textbf+\,}}{\frac{{\mathtt{51}}}{{{\mathtt{97}}}^{{\mathtt{2}}}}} = {\mathtt{1\,435.248\: \!592\: \!197\: \!510\: \!098\: \!2}}$$

$${\sqrt{{\mathtt{82}}{\mathtt{\,\times\,}}{\mathtt{65}}{\mathtt{\,\times\,}}{\mathtt{\pi}}}} = {\mathtt{129.401\: \!270\: \!641\: \!495\: \!6}}$$

$${\mathtt{129.401\: \!27}}{\mathtt{\,-\,}}{\mathtt{1\,435.248\: \!59}} = -{\mathtt{1\,305.847\: \!32}}$$

x= -1305.8 correct to 1 decimal place
